A new study conducted by Duke University has shown that the chemicals in nail polish can enter the bloodstream in significant amounts within just two hours of application! These chemicals can contribute to infertility, hormone-related cancers such as breast and ovarian cancer, thyroid disorders, neurological issues, and even diabetes.
Some may argue that nail polish is applied only occasionally and that exposure to toxins in such small amounts does not pose risks, but nail polish is just one of the beauty products that women regularly use. When you add up the exposure to toxins from nail polish, no matter how small or large, with those from perfumes, cosmetics, body lotions, and many others, it can no longer be considered insignificant.
Nails are permeable to most molecules, and TPHP (the chemical used to make nail polish more durable) is absorbed into the cuticles or around the nail, says Johanna Congleton, a principal researcher at EWG who worked on the study.
Formaldehyde is a well-known carcinogen that can cause respiratory discomfort if inhaled. Symptoms of exposure include coughing, asthma, and itching. Formaldehyde is used in nail polish to provide firmness and preservation.
DBP (Dibutyl Phthalate) is a plasticizer and solvent that is also an endocrine disruptor. Chronic exposure through ingestion can lead to liver and kidney failure, especially in children.
Toluene, a skin irritant, has been considered a toxic hazard. This chemical is dangerous for breastfeeding women or expectant mothers, as it can be absorbed into the bloodstream and enter breast milk. Upon inhalation, the chemical can cause drowsiness, headaches, and irritation of the respiratory tract. Toluene is used in nail polish to give it a smooth appearance.
The substances are not only a concern for women who use nail polish but also for those who work in beauty salons and are exposed to these substances day in and day out. The good news is that since 2006, several major cosmetic companies have announced that they will phase out these three substances.
The label does not always reflect the ingredients, says researcher Valetti Lang, interim director of the California Department of Toxic Substances Control. A study found that even “toxin-free” nail polishes can have high levels of these toxic chemicals.
There are no regulations in this industry, allowing cosmetic manufacturers to use any combination of chemicals they wish. Additionally, professional products found in salons are not required to provide their clients with even basic information about the ingredients contained in their products.
Simply buffing the nails with a special file can make them look nice and shiny without the need for nail polish. A bonus of natural nail buffing is that it can help your nails grow stronger and longer due to increased circulation, so you won’t have to worry about breaking them anymore.
